检查元素显示时，Bitrise上的Appium iOS返回false

Question

目前，我正在使用WebDriverWait（XCUITest）等待在iOS应用上显示元素。

WebDriverWait wait = new WebDriverWait(driver, 15);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.name("priority 1 program")));

这适用于本地计算机，但不适用于Bitrise服务器。 使用Bitrise的日志，我意识到Appium确实返回了元素（已找到）但未在屏幕上显示（isDisplay返回false）。

所以我检查了屏幕截图，令人惊讶的是显示的元素没有任何重叠的视图。

我已尝试过不同类型的环境，但情况相同。

• mac os 10.12.6,10.13.2
• appium 1.7.2,1.7.0
• Xcode 9.2,9.0.1
• iOS 11.2，iOS 11.0

我也从互联网上进行了一些搜索，但似乎没有解决方案可行。

感谢任何帮助，谢谢。

有几个与元素可见性相关的未解决的问题，它可能与 WebDriverAgent 中的issue或您提到的那个相关，但仍未修复。

作为一种解决方法，您可以：

• 将 simpleIsVisibleCheck 功能设置为false并检查是否有帮助
• 切换到import { Component, OnInit } from '@angular/core'; import {HttpClient} from "@angular/common/http"; import {alarm} from "../shared/alarm.model"; import { DataTableResource } from 'angular-4-data-table'; @Component({ selector: 'app-alarm-data-table', providers:[], templateUrl: './alarm-data-table.component.html', styleUrls: ['./alarm-data-table.component.css'] }) export class AlarmDataTableComponent implements OnInit { alarmsData = new DataTableResource(this.alarmsData); alarmCount:number =0; constructor( private http: HttpClient) { } ngOnInit() { this.http.get<alarm[]>('http:my api '). subscribe(data => {this.alarmsData = data ; this.alarmCount =data.length ;} , error2 => {console.log('Error has occured'); }); } } 并且基本上只等到元素存在，跳过 </data-table-column> <data-table-column [property]="'naturalId'" [header]="'Natural'" [sortable]="true" [resizable]="true"> </data-table-column> </data-table> </div> 属性
